Many people with disabilities in the world's poorest countries are unable to attend school or find work. Barriers such as stigma or a lack of support prevent them from realising their full potential.
Community projects, supported by UK aid, attempt to tackle these barriers by investing in, and improving, the lives of those living with disabilities.
Meet the people whose lives have changed through these programmes.
In Bangladesh, 25-year-old Halima was born without a left hand. Her parents could not afford to send her to school.
Thanks to a charity called UCEP Bangladesh, Halima has learned technical skills in garment finishing and quality control. She now has a job earning £76 ($100) per month.
She says, "I am happy, I am not a burden to anyone any more. I can even help my parents."

Shaher was buried alive after being shot at the start of the Syrian conflict. He was presumed dead.
But when his cousin came to identify his body, he saw that he was breathing. He pulled him out and took him to hospital.

Sylvia has experienced first-hand how tough life can be when you have a disability. When she became blind, her husband started to see her as an unwanted burden. After years of domestic abuse she was forced to leave home.
Today, Sylvia has a new home in the provincial town of Masindi, Uganda, along with a regular job. She teaches her disabled students how to use a knitting machine, sharing her skills with others. This gives her students the opportunity to support themselves.
By doing this she helps others to avoid the misery she endured for so many years.

During a fierce battle in 1996, a bullet pierced his temple, shattering his skull and lodging behind his left eye, leaving him permanently blind. A decade later, he has turned his life around, and is now fighting to overturn attitudes towards the blind in Uganda.
A team of British International Citizen Service (ICS) volunteers spent three months working with the deaf community in Nandi County, Kenya, to raise awareness of deaf rights and increase integration of the deaf and hearing communities.
Poverty, prejudice and limited resources mean deaf people in Nandi are often marginalised and miss out on the support they need.
The volunteers worked with a number of different community organisations to teach Kenyan Sign Language and increase deaf awareness, and to challenge the stigmatisation of deaf people.
They also organised a deaf awareness march in Kapsabet. A mix of deaf people and hearing supporters, including pupils from the Kapsabet School for the Deaf, called for more support, rights and resources for deaf people, including better education and employment opportunities.
The UK government's first Global Disability Summit is on 24 July.
